This research is intended to observe the effect of through sociodrama technique in improving students’ interpersonal communication skill at the tenth-grade students of SMK Ar-Rahman Misriadi Langkat. In the research methodology, the writer used quasi-experimental design, focusing on non- equivalent control group design. In addition, to decide the sample of the research the writer used non-probability sampling technique in the form of purposive sampling technique. There were twenty four  male students who had been chosen as the research sample.The sample chosen was classified based on the interpersonal communication  skill in the lower rate. Moreover, the instrument used to decide the sample was the instrument of interpersonal communication skill which provided four options on a Likert scale. The technique of analysis was carried out by using descriptive statistics which provided empirical mean to know the average scores between the pre-test and the posttest in the experimental group and controlled group respectively. The result showed that the score of Asymp. Sig were 0.000 which meant that the interpersonal communication skill of the male students Sig < 0.05. It can be concluded that the high number of increasing of interpersonal communication skill was experienced by the male students  in the experimental group than in the controlled group. Therefore, the result of this research was used to improve the interpersonal communication skill of the tenth- grade male students  at SMK Ar-Rahman Misriadi Langkat.

The purpose of this study was to look at the effect of realistic mathematics learning on students 'reasoning abilities and to determine students' responses to mathematics learning with realistic mathematical approaches and their relation to mathematical reasoning abilities. This research was conducted at YPAK Galang of Junior High School at 2017/2018 Academic Year. The method used in this study is a quasi-experimental method with the design of Non Equivalent Control Group Design. The sample in this study was 64 students consisting of 32 students for the experimental group and 32 students for the control group. The data analysis technique used in this study is a regression test. Based on the calculation of hypothesis regression linearity test (i) Ha is accepted and Ho is rejected because F_count < F table is -44.40 < 1.88 then the regression form is linear, and for testing the significance of hypothesis regression (ii) Ha is accepted and Ho is rejected because of Fcount > Ftable that is 44.402 > 3.96 means that there is a relationship of variable (X) to varabel (Y). Data collection techniques in the form of a questionnaire consisting of 14 items statement. Based on the calculation of questionnaire data on students 'responses to realistic mathematical learning, the percentage of students' responses that stated yes was 75.38% and the percentage of responses that stated was not 24.62%. This shows that the student response questionnaire is positive.

This research was conducted because the students' self-efficacy in mathematics was still low. The Brain Based Learning approach is expected in solving this problem. The purpose of this study was to determine and analyze the increasing in self-efficacy of students who received the Brain Based Learning (BBL) approach in mathematics. This study is a quasi-experimental study with a nonequivalent control group design. The population of this study were all students of grade VII at a junior high school in Padang City. The sample was determined by purposive sampling technique. The data collection instrument in this study was a non-test (questionnaire). Questionnaires are used to measure students' mathematical self-efficacy. The questionnaire is based on indicators of self-efficacy. The self-efficacy questionnaire consists of 28 questionnaire items. The questionnaire was given before being given treatment and after being given treatment. The treatment given was in the form of mathematics learning based on the BBL approach. The result of this study is that the increase in self-efficacy of students who get the BBL approach learning is significantly better than learning with the conventional approach as a whole.

The existence of laboratory activities in or outside the room can facilitate students in visualizing the imagination to be real. This study aims to determine the effect of using practicum methods on the students' representation ability and cognitive learning outcomes on the subject matter Classification of Living Things. This research was conducted at Junior High School 26 Bandar Lampung. The method uses a quasi-experimental method with Pretest-Posttest Non-Equivalent Control Group Design. A random sampling technique took the sample in this study, and the research subject uses class VII A as experiment class and VII B as a control class. The data in this study are quantitative data that were analyzed using the Independent sample t-test. Based on the results of this study, the effect of practicum methods on the students' representation ability is level 1, and 2 before the treatment then increases to levels 3, 4, and 5 after the practicum with the student answers that have made elements representation such as tables, graphs, icons, and images. Therefore, practicum methods can be used by science educators to facilitate students in conceptual understanding by using elements of representation.

A quantitative research study to assess the effectiveness of breast crawl in initiation and maintenance of effective breast feeding among newborns in selected hospital at Kollam. The objectives of the study were to assess the effectiveness of breast crawl in initiation of breast feeding among newborns, to assess the effectiveness of breast crawl in maintenance of effective breast feeding among newborns and to find the association between the breast crawl of new born with the socio demographic variables. A quasi experimental non-equivalent control group design was used for the study. Purposive sampling technique was used to select 60 newborns born by normal vaginal delivery who were alternatively posted as experimental group and control group. The tools were demographic proforma, observation checklist for breast crawl, observation checklist for initiation of breast feeding and observation checklist for maintenance of effective breast feeding. Breast crawl given to the experimental group and assessed the initiation of breast feeding. Routine initiation of breastfeeding given to control group. Continuation of breast feeding was assessed equally in both groups, for six feeds in a day for 3days. The unpaired ‘t’ value was used to assess the effectiveness of breast crawl in initiation of breast feeding. The calculated ‘t’ value, (14.47) was greater than table value, (2.660). Effectiveness of breast crawl in maintenance of effective breast feeding was assessed by using unpaired ‘t’ value. The calculated t value in Day I (8.6551), Day II (18.55) and Day III (19.24) were greater than table value (2.660) at 0.05 level of significance. It concludes that there was effectiveness of breast crawl in initiation and maintenance of effective breast feeding among newborns. There was also progressive increase in the second and third day.
